Re: smtp questions

I changed my code to:

Dim message As New System.Web.Mail.MailMessage()
message.From = "asdcb1@uaa.alaska.edu"
message.To = "cis410webportalgroup@yahoogroups.com"
message.Subject = "HiTechAlaska Newsletter"
message.Body = tboxnews.Text
SmtpMail.Send(message)
message.To = "dennis@design-pt.com"
SmtpMail.Send(message)
SmtpMail.Send("HiTechAlaska", "asdcb1@uaa.alaska.edu", _
"HiTechAlaska Newsletter", tboxnews.Text)

when I went to check my email, I got all three emails and your
suggestion. Thanks.
